What it is

Flesch-Kincaid Readability & Grade Level Analyzer is a free web calculator for estimating how readable English text may be. It calculates Flesch reading ease and Flesch-Kincaid grade level from sentence, word, and syllable counts. Results include both scores alongside the word, sentence, and estimated syllable counts, with a button to copy them. The page also offers sentence analysis and clarity recommendations, framing its scores as a quick, rough proxy and suggesting shorter sentences and more common words as ways to improve them.

Syllables are estimated by counting vowel groups rather than looking up pronunciations, so silent vowels, unusual spellings, and non-standard pronunciations can throw off the count. The formulas address sentence length and syllable mechanics; they do not assess logic, jargon, tone, or overall clarity. No account is required. Veomark says most of its tools run in the browser and core inputs are not uploaded to its servers, though Google Analytics 4 may use cookies or similar technologies. The calculator lists no integrations. Its plan is free. For privacy questions, Veomark directs visitors to contact the domain registrar or hosting account holder listed for veomark.com.
